In verse 26 of chapter 38 Of The Holy Quran, King David is warned not to follow his worldly desires as they will lead him away from Allah.
This applies to all of us. One desire is for ease and comforts of this world but the struggle for comforts of this world leads one away from Allah. We have to get up early to pray and lose the comfort of our warn bed, forgo food and drink and give away part of our hard earned money in charity. There is no way to get closer to Allah except to struggle against our worldly desires.
